I think they need a better way to sift the wheat from the chaff.

Numbers can be magic and eight bytes is enough of a taste to tell honey from vinegar.


Nice find

I see. I have seen this kinda behavior from vendors too often. I supose the reason for this is the flood of false

Congrats for your work!

I was basically told that Facebook didn't see it as an issue and I was puzzled by that. Ends up the Facebook 
security team had issues
reproducing my work and that's why they initially disgarded it. After publishing, the Facebook security team 
re-examined the issue and by
working with me they seem to have been able to reproduce the bug.

Not fixed yet. At least not yesterday when I checked.

Nathan, didn't Facebook ask for some time to fix this bug after they have acknowledged it?
